  • the sound-reducing component has at least one absorption chamber on, which is fluidly connected to the air flow.
  • silencers are available in different versions and materials as an intermediate piece in the conduit between two pipe sections set.
  • DE 199 56 165 A1 describes a device for reducing airborne noise Flow noise of e.g. Turbochargers on internal combustion engines disclosed that is composed of an outer tube and inner tube.
  • the outer jacket is like this shaped that either only one chamber or a series of chambers with partitions as well as two connections are formed. It is described that have the required fastening systems attached directly to these connections.

  • the flow-related Noises are in a predetermined - low - range.
  • the air guide tube is connected to a special connector coupled the internal combustion engine, which is designed as a connection / damping unit is.
  • This separate connection / damping unit is not used as an adapter between two pipe parts of the air duct, but directly as a connector connected to the internal combustion engine, in particular a turbocharger.
  • the connection / damping unit is made in one piece and has a connection element a quick coupling and an inlet as a damping element. The inlet will inserted from the outside into the connection-side pipe end to form an annular space, until the quick coupling on the joint surface of the pipe end to the system comes and is fastened.
  • the absorption chamber is between the particular according to the contoured inlet and the inner wall of the air duct and thus trained close to the connection.
  • the connection / damping unit and / or that Air duct are made in particular from the same metallic material, like steel, especially stainless steel, or aluminum, and can even handle the high Withstand temperatures and pressure peaks in the immediate vicinity of the turbocharger.
  • connection / damping unit Reduce due to the integral design of the connection / damping unit the number of components to be connected and thus the necessary connection points or welds clearly, which increases productivity and the susceptibility to leakage reduced. There are higher strengths of the entire air duct and the connection / damping unit.
  • connection / damping unit Air guide pipe quickly and tightly with the due to the quick coupling Turbocharger can be connected.
  • the damping element is integrated in the connector is, the further guide tube can be flexible beyond the damping area what, in particular, its three-dimensional design for the individual available space in the engine compartment. Small and complicated Construction spaces can be optimally used.
  • the damping element is integrated more centrally in the air duct, but in the connection side In the end, the material wall thickness of the pipe can vary depending on strength requirements adapted quickly and without complicated design changes become.
  • a preferred design form of the inlet of the connection / damping unit sees proposes that on the one hand it has a first - preferably hollow cylindrical - section Has perforations or openings, the cross section of which is smaller than the cross section of the pipe end is. On the other hand, it has adjacent second sections for this purpose on. These second sections are expanded in a ring shape in such a way that they are fluid-tight come to rest on the inner wall of the air duct and thus act as a flow barrier Act. Part of the air flow is through the openings of the first Section passed into the absorption chamber in the annulus between the first Inlet section and the outer tube wall is formed.
  • connection / damping unit is manufactured in one piece and includes the quick coupling and the inlet.
  • the one-piece combination element is an inlet, with which several absorption chambers can be formed.
  • the first and second alternate Sections of the inlet molded in one piece.
  • it can one-piece combination element of quick coupling and inlet, starting from a base unit, in modules with one or more inlet processes, each comprise at least a first and a second inlet section, depending on the requirement be extended. Accepting another connection this way a high variability in the number and shape of absorption chambers is achieved.
  • the properties of the damping can be determined by the length and / or shape of the first Inlet sections, i.e. of the sections containing the openings, and the second Sections and thus the resulting absorption chamber shapes and volumes can be set.
  • the quick connector itself is a widened tube that matches the geometry of the connector of the turbocharger is adjusted.
  • the Quick coupling also has a sealing function thanks to an integrated sealing ring.
  • the proposed component for reducing noise emissions in the form of a connector can basically with any air duct with a matched Diameter can be combined.
  • the air duct can over its Length of any curved three-dimensional contour and / or any Have cross section, which increases its variability in terms of space.
  • the contour of the air duct can also affect the absorption chamber volume and shape Influence that surrounds the inlet as an outer tube on the connection side.
  • the air guide tube is preferably hollow cylindrical over the damping area. It can also be contoured and, together with the inlet, the absorption chambers form.
  • Fig. 1 shows schematically in the overall view an air duct 1 with an integrated Sound resonator or damping element 2.
  • the damping element 2 is part of a at the end 3 of the pipe attached connection / damping unit 4, the same time a quick coupling 5 for direct connection to a turbocharger (not shown) having.
  • the connection / damping unit 4 or the connection piece takes over thus connection and damping function.
  • the air duct 1 itself can either the supply duct for fresh air or the air loading pipe and / or the discharge duct for exhaust gases.
  • the noise damper or the damping element 2 is inserted into the connection side Pipe end 3 inserted inlet 6 together with the surrounding Inner tube wall 7 (see also Fig. 2 and 3) formed. Between that accordingly contoured shaped inlet 6 with perforated sections 8 and the inner tube wall 7 form absorption chambers 9, 10, which conduct fluid with the air flow (see arrow P) are connected.
  • absorption chambers 9, 10 which conduct fluid with the air flow (see arrow P) are connected.
  • the dashed arrow indicates that this Air duct can also serve as a discharge duct for gases. Because the damping element 2 or the inlet 6 on the connection side in the form of a connector with the air duct 1 is connected, that can go beyond the damping area 11 Air duct 1 adopt any design. 1 shows one possible installation of the air duct 1 with the appropriate bracket 12.
